The big news today out of BlizzCon is that StarCraft II is being divided into
Terrans: Wings of Liberty, Zerg: Heart of the Swarm, and Protoss:
Legacy of the Void, three separate standalone campaigns that will be sold
separately, each highlighting one of the game's races, with the decision to
subdivide the real-time strategy sequel said to be the alternative to either
delaying or scaling back the release.
Shacknews quotes
Blizzard's Rob Pardo saying the second and third games "will be like expansion
packs, but we really want them to feel like standalone products." Word is the
Zerg campaign will emphasize RPG elements, the Protoss campaign will focus on
diplomacy, and the Terran campaign will also feature a Protoss mini-campaign.
Shacknews also offers
a couple of cut-scenes, one fully rendered, and the other using the game engine.
